IMPROVEMENT IN SEAMS FOR LEATHER-WORK.

Specification forming part of Letters Patent No. 139,429, dated May 1873; application led November 2, 1872.

. To all whom tt may concern:

Be it known that I, SAMUEL W. SHOREY, of Boston, iu the county of Suffolk and State of Massachusetts, have invented an Improved Seam for Leather -Work; and I do hereby declare that the following, taken in connection with the drawings which accompany and form part of this specication, is a description of my invention sufficient to enable those skilled in the art to practice it.

United States Letters Patent No. 131,308, dated September 10, 1872, have been granted for my invention, consisting in a Seam for leather-work, made up of metal staples, the points of each Staple being twisted together to Secure them. In my present invention I dispense with the use of staples, and employ, instead of staples, wires or nails, and the points of adjacent nails I twist together. The fastenings may be composed of headed nails or may be cut (as they are driven) from continuous wires, as in sole-nailing machines, and when cut from wire adjacent points may be twisted together on both sides of the work.

My invention consists in aseam, the fastenings of which are composed of a series of single nails, alternate points of the series being twisted together to clinch the nails'.

f The drawing represents a seam embodying the invention.

Figure 1 shows a view of the outer side of f the work. Fig. 2 is a section, (enlarged.)

c b denote the two pieces united by the fastenings. c c denote the nails. Each nailc has a head, d, that holds against the outer face of the Work, and a shank, e, that passes through the work, and the points of adjacent y nails (in pairs) are twisted together and iiattened against the inner face of the work, the

points of the first two nails being thus c0n` S. W. SHOREY.
